Title: Manufacture of linear superconductive material
Inventor: YAMAMOTO SUSUMU
IPC: H01B13/00
Filed: 1988-05-06
Abstract: PURPOSE:To facilitate manufacture of sintered superconductive material as a wire in practical application having high critical temp. by accommodating Ir2O3 in a metal cylinder together with material powder in a manufacturing process, in which material powder is sintered in the metal cylinder. CONSTITUTION:Ir2O3 dissolves at a temp. over 400 deg.C and emits oxygen to supply oxygen to the material powder which is required at the time of sintering. A plasticible metal cylinder is used with one end closed, and wire stretching or forging turns it into required form while the material powder is held in the cylinder at an appropriate density. Prior to filling of material powder, the Ir2O3 is attached to the inner surface of the metal cylinder, and it is desirable that the substance produced after supply of oxygen does not react with the sintered substance. By this method, a wire can be manufactured by practical method in which a sintered substance having high superconductivity is accommodated in a metal cylinder having substantial mechanical strength and plasticity.

Title: Output control method for sequence controller
Inventor: YOSHIDA TATSURO
IPC: G05B19/05
Filed: 1980-08-13
Abstract: PURPOSE:To prevent a main controller from uneffective stop by outputting an operation result processed by a dual system once to the external and inputting the output again to operation processing parts through a digital input part to drive a pulse generating circuit. CONSTITUTION:An output controller 8 conducts the dual output processing of operation results 15 and 16 outputted from operation processing parts 3 and 4 and outputs the processed result 17 to the external. The signal 17 outputted to the external is read again by an input part as a condition 18. The controller 8 finds AND between the condition 18 read in the processing parts 3 and 4 and the opeation results 15 and 16 previously outputted from the processing parts 3 and 4 and, when AND is formed, drives an interruping circuit 22. Thus, the controller 8 outputs the interrupting output 21 of a prior system to an external device 11 to be controlled at the normal time while conducting the fault diagnosis of the previously fixed operation parts through its backup system and, at the abnormal time, switches the interrupting output from the prior system to the backup one to operate the external device 11 to be controlled.

Title: Electron beam emitter
Inventor: KODERA MASATOSHI
IPC: G21K5/10
Filed: 1994-05-25
Abstract: PURPOSE:To enable the simultaneous irradiation over the whole circumference of a sample with one accelerator by accelerating electron beams radiated respectively from each of electron sources in an accelerating electric field. CONSTITUTION:Electrons radiated from electronic guns 7 are extracted through holes 11 of an electron source cover 16, and are accelerated toward a metal thin film window 13 by a direct current electric field formed in a vacuum container 2. In this process, the appropriately designed geometric dimensions of the cover 10 guides the electron beam to the window 13. The electrons accelerated in the container 2, which are accelerated toward the axial arbor of the container 2, pass through the window 13, when the ratio of electron beams passing through it is increased by appropriately selecting a geometric arrangement of the guns 7 and the cover 10 and a value of the electric field. When they pass through the window 13, moreover, the electrons are scattered by metal molecules in the metal thin film and radiated into the air in an inner wall 4 and are further scattered by molecules in the air, diffuse rapidly and collide with a sample 18 to be irradiated. Therefore, when electrons reach the sample 18, they have much larger beam sections than when they pass through the container 2, which enables the electron emission in a uniform dose over the whole surface circumference of the sample 18.
